Vedic mathematics is an ancient system that allows for instant mental calculations of various mathematical problems through simple techniques. Some key techniques include using vertical and crosswise multiplication to avoid memorizing full multiplication tables, squaring numbers ending in 5 by multiplying the first number by the "one more than" number, and methods for multiplication, division, time conversions, temperature conversions, and unit conversions that reduce steps compared to standard algorithms. Vedic mathematics aims to help students solve problems more quickly, reduce memorization burden, and increase concentration through its unique calculation rules and principles.

1. VEDIC
MATHEMATICS

2. What is vadic maths?
 Vedic mathematics is the name given to
the ancient system of mathematics
 It’s a unique technique of calculations
based on simple principles and rules , with
which any mathematical problem - be it
arithmetic, algebra, geometry or
trigonometry can be solved mentally

3. Instant calculations:
All from 9 and the last from 10 to perform
substractions.
e.g.1000-457=543
 VERTICALLY AND CROSSWISE you don’t
need to the multiplication tables beyond 5x5.
e.g. 8x7;7x6;

4. Instant calculations:
 VERTICALLY AND CROSSWISE to write
the answer straight down!
e.g.
Multiply crosswise & add to get the
numerator, & multiply the denominators to
get the denominator.

5. Instant calculations:
 Quick way to square numbers that end 5 =>BY
ONE MORE THAN THE ONE BEFORE.
e.g.
i)The first number (7)multiplied by the
number”one more”,which is 8;
ii)Is always25;

6. Instant calculations:
 Method for multiplying numbers where the
first figures are the same and the last
figures add up to 10.
e.g.
i)We multiply 3x4=12;
ii)We multiply the last figures;

7. Instant calculations:
 Multiplying a number by 11.
e.g.26 x 11=286;77x11=847;
i)we put the total of the 2-figures between
the 2-figures;
 Method for diving by 9.
e.g.43/9=4;232/9=25,(r.2+3+2=7)
i)The first figure of 43 is 4=>the answer
ii)Reminder 43=>4+3=7

8. Multiplaying by 12-shortcut
 e.g. 12 X17;
i)We multiply the 1(of12)by the number
we’re multiplaing =>1x17=17;
ii)Then => 17x10=170;
iii)Multiply the 2x17=34;
iv)Add 170 +34=204;

9. Is it dividible by 4?
 For 4 to divide into any number we have to
make sure that the last number is even;
e.g.1234/4=?
i) 4+(2x3)=10 =>4 goes into 10,two times
with a reminder 2,doesn’t go in evenly;
but, 212334456/4=?
i) 6+(2x5)=16,&4 goes in 16 evenly;

10. Adding time 
 A simple way to add hours and minutes
together:
 Let's add 1 hr and 35 minutes and 3 hr 55
minutes together.
i)135+355=490
ii) No matter what the hours and minutes
are,just add the 40 time constant to the
sub total.
=>490+40=530 (finaly 5h.30min)

11. Kilos to pounds
 How to convert Kilos to Pounds, & Vice
Versa?
 Converting Kilos to pounds:
e.g.86 kilos into pounds:
i)Multiply the kilos by 2;
=>86x2=172;
ii)Divide the answer by 10;
172/10=17,2;
iii) i)+ii)=189,2;
=>86kilos=189,2pounds

12. Temperature conversions
 This is a shortcut to convert Fahrenheit
to Celsius and Vice Versa;
 e.g.74°F=?°C
iii) 74F-30=44;
ii)44/2=22 °C;
⇒ 74 Fahrenheit=22Celsius

13. Converting Kilometres to
Miles
 Useful method for when travelling & need
to know what kilometres to miles are;
 Formula=> number of (km / 8 ) X 5
 e.g.80 km into miles;
=>(80/8)x5=50 miles

14. To sum up:
Vedic Mathematics is becoming popular
all over the world due to the following:
* It helps a person to solve problems
10-15 times faster.
* It reduces burden (Need to learn tables
up to nine only)
* It provides one line answer.
* It is a magical tool to reduce scratch
work and finger counting.
* It increases concentration.
* Time saved can be used to answer more
questions.
